Instead of finding a good SaaS idea, I would rephrase the question to finding a valuable problem to solve, a problem which people are very willing to solve in exchange for other resources like money. In school, we are trained to solve a problem very well. But the problems are given by teachers. There is no one to train you finding a valuable since kindergarten. That's why it's so hard to find it as an adult.
